UNITED STATES PATENT OFFICE.

R. S. HARRIS, OF GALENA, ILLINOIS;

RUDDER.

Specification of Letters Patent No. 17,572, dated June 16, 1857.

To all whom it 'may concern:

Be it known that I, ROBERT S. HARRIS, of the city of Galena, county of Jo Daviess, and State of Illinois, have invented a new and Improved Modeof Steering Steamboats and Vessels; and I do hereby declare that thefollowing is a full and exact description, Ato wit:

In order that ship carpenters may construct my double action jointedrudder, I give the following description:

In constructing the rudder I first take the ordinary rudder, and shortenit about one third, more or less, then insert through the saine,horizontally at C and D two iron rods with eyes in the stem or outerend. I also insert rods of the same description at correspondingdistances through the outer rudder F as shown at C, D, with the eyestoward the bow or front end so that when put together, and a rod passedthrough they form the hinge upon which it turns.

The tiller of the outer or second rudder F can be attached withstirrups, or in any ot the ordinary methods, and should be as long as itwill work clear of the main rudder post, and the end attached to a ropeor chain, or other equivalent and way between the guards or davits, theouter end of said chain drawn taut and made fast to the guards ordavits. I also use in the chains midway between the point of attachmentto the guards and the tiller of the second rudder, a screw swivel forthe purpose of slackening or tightening the same as necessity mayrequire. Thus constructed and attached it is operated in the same manneras the ordinary rudder.

Having thus briefly described the manner of constructing and operatingmy inven tion, what I claim as my invention, and desire to patent is 1.The application of an outer or second rudder attached to and working onthe co1nmon rudder.

2. I also claim the short tiller held and worked by stationary chains orropes, as above described for the purpose above named.

Dated at Galena Feb. 9, 1857.

ROBERT S. HARRIS.
